And depending on if Lyte ever sees the use of it a white ribbon should be for someone who's obtained all 4.
In all seriousness, we're still working on additions to the Honor Initiative. There's no current plans to allow players to display multiple ribbons because it's actually visually noisy in many of the solutions we've seen.
Our first priority for Honor is to re-balance the ways to unlock Crests. We feel Honorable Opponent is a bit too easy to unlock and currently too common and the other 3 Crests are too rare. However, we're pretty happy that players who have unlocked Great Leader, Mentor or Great Teammate have actually been extremely positive players on average--we've gotten great feedback from players who have been in games with these Honorable players.
Our goal is to make the other 3 Crests a bit easier to unlock while still maintaining the high quality of positive behavior we're seeing in players who have already unlocked them.
